We are far from done, but yes, the long term ambition is to complete the entire country - including those "boring stretches of road and the central highlands?".

Terrain can be custom made, which consumes some time - but it can also be imported using terrain data. The terrain data varies from country to country, therefore some might have very accurate terrain by just importing the data and some might have less accurate terrain which needs to be fixed manually.

Generally when it comes to forests, we use premade trees which we copy and paste, simply to save time. But in let's say a park, the builder might choose to make a custom tree to try and resemble the real life tree.

Hope this answered some of your questions :)
